We have already demonstrated how to do this, right here in sci.crypt. If 
you think it cannot be done, it is you who are naïf.

The weakness of your cryptography lies in key re-use, inevitable because 
the key is so vast and so difficult to change (requiring as it does the 
editing and recompiling of source code), and your cipher is 
insufficiently robust to withstand the cryptanalysis of multiple 
messages encrypted with the same key).

And I doubt whether anyone here would trust you to produce multiple 
ciphertext messages all encrypted with the same key.
